Abstract: ABSTRACT OF THE DISCLOSURE           An improved tire-slip preventing device consisting of a plurality of cross belts arranged across a pair of paral-lel cords in the form of a ladder is constructed so that one end of every other cross belt can be detached from the asso-ciated cord.  The detachable end of every other cross belt is attached to the associated cord after the device has been wrapped about the tire, whereby a very tight fit between the tire and the device can be easily obtained.  The last cross belt at one end is made detachable or otherwise one of the cords is provided at an intermediate portion thereof with a separable link, thus permitting the device to be wrapped about the tire without raising the vehicle or driving it onto the device.

Abstract: APPARATUS AND METHOD FOR STEAM DRYING                         Abstract A method and apparatus are disclosed for drying materials by contact with a drying gas consisting essentially of internally generated superheated drying steam above 212°F., to vaporize the water in the material and remove it to produce the steam used for drying.  A minor portion of steam is removed from the drying gas and discarded to maintain pressure equilibrium.  The drying steam is produced within the drying chamber from water evaporated from the material being dryed and is either heated to form the superheated steam within the drying zone where it is in contact with the material or removed from the drying zone, heated to form superheated steam, and returned to the drying zone for contact with the material during drying.  A wood veneer dryer employ-ping the invention is described as well as an apparatus for drying particulate material.  The drying zones pro-vided with the veneer dryer have at least along the major portions of their lengths a negative internal pressure which is below that of the ambient external atmosphere outside the dryer to prevent pollutants from leaking out of the dryer and ambient air is prevented from entering the dryer into such drying zones.

Abstract: TEST STATION APPARATUS                      ABSTRACT OF THE DISCLOSURE           Electrical currents and potentials in test leads associated with underground piping, cables and the like are monitored by a test station apparatus which essen-tially includes a tubular plastic conduit for sub-terranean implantation while the upper end of the conduit and test leads are accessible from aboveground. A plastic tube projecting from diametrically-opposed sides of the conduit provides one form of anchor means to maintain the conduit within the ground while in another form the anchor means consists of a collar retained on the lower end of the conduit by a sleeve. A collet-type compression fitting is used to attach a collar onto the upper end of the conduit. Pedestals extend vertically from the end wall at opposed sides of an annular opening in the collar. The pedestals support a terminal block extending across the annular opening so that test leads passing vertically along the conduit are attached to either side of the terminal block by terminals which are normally enclosed by a dome-shaped cover secured to the collar.

Abstract: Abstract A sleeve bearing is described which is useful for carrying the rotating propellor shaft of water craft, as well as for various industrial purposes.  The sleeve bearing consists of a single homogeneous solid, hard elastomeric urethane polymer having a Shore D hardness of at least 60, a compressive modulus of elasticity at a 4% compressive strain of at least 50,000 psi and a dry dynamic co-efficient of friction against steel of no more than 0.20.  This polymer is machined so as to fit within a cylindrical housing by means of a forced interference fit providing sufficient outward radial force by the outer surface of the sleeve on the housing to retain the bearing in movement-free fit during the operational life of the bearing.

Abstract: U.S. 907,928 ABSTRACT OF THE DISCLOSURE   This invention relates to improvements in a process for treating a catalyst, or bed of catalyst, comprised of a composite of an iridium metal or admixture of said metal with other metals, particularly platinum, or admixtures of iridium and platinum with other metals, halogen, and a refractory porous inorganic oxide, notably alumina which has been deactivated by coke de-position thereon.  The time required for reactivation of such catalyst can be shortened by deliberate agglomeration of the iridium, or admixture of iridium and other metal hydrogenation-dehydrogenation components, above about seventy percent, prior to one or more cycles of sequential reduction/ halogenation treatments.  The desired high agglomeration of iridium, or admixture of iridium and other metal hydrogenation-dehydrogenation com-ponents, is preferably accomplished by a relatively severe coke burn.
